My New Isekai!

"Where am I…?" I asked myself as I sat inside pure darkness.

"Haru, Haru. Can you hear me?"

"Who is this…?"

"Nobody important, but in a few moments, your body won't be in your control. Please listen to me if you don't want your friends to lose their lives."

"What are you talking about?!" I shouted into the never ending tunnel of darkness.

"..." the voice silenced. Along with Zim suddenly coming out of nowhere.

"Haru." Zim said with utmost seriousness.

"Yes…?"

"Okay, you may or may not be taken over by a person called Jack the Ripper."

"Jack...the Ripper?"

"Yeah."

"Why are you telling me this?"

"Because. At this moment in time, I just destroyed your body. And maybe, just maybe I didn't 'destroy' but I cut off a lot of oxygen, blood, and all round good stuff for the human body to function from your hands."

"Sounds perfectly normal - wait, what now?"

"No time to explain. At this time your body is slowly rising, not from pain, but your body taking a full on deal of stress on your nervous system. Your body is trying to heal it with my power."

"How does that work?!"

"I gave you some of my blood, that blood multiplied when it entered your bloodstream and somehow, your blood didn't have a deadly reaction with getting a different type of blood."

"So, I'm 'currently 'healing' where exactly?"

"Ahem, mansion."

"Wait. Where Kura and Megumin are at?!"

"Yes."

"You effing idiot!!" I exclaimed through the echoes of the abyss. "Why did you do that right there of all places?!"

"They told me to do it, Haru."

"Oh...okay, I guess? But what's happening out there?"

"Currently, your skin just peeled off and black veins are covering your white skin."

"Mmm. How long before I go back to my body?"

"I dunno."

"Don't give me 'I dunno,' you're the one that is breaking my body!"

"Fine. Give it a few-"

Zim got cut off by a rumbling.

"What...was that?!"

"Nothing."

"Don't say that! Do you think I didn't feel that?!"

Zim let out a frustrated sigh. "Fine."

Suddenly I fell into the back abyss more and more. Moments later, I was back into my body, or back in control.

"Haru…?" Kura asked.

"Yep?"

"Um, are you good?"

"What do you mean?"

"Look at your hands…"

I looked down at my hands and saw that they were completely messed up. "What the…?" I said to myself.

Zim came out of nowhere. "This is why I didn't want to bring you back. Your hands are currently looking you put them in a deep fryer."

"I can see."

After staying still for a bit, I stood up. My hands didn't feel too different, they just felt chapped.

"Haru. Can you tell me what Jack the Ripper meant by, 'four'?"

"Yeah…I got kidnapped, and you know...killed the man?"

"You say that so calmly, Haru…"

"Well...it wasn't that hard of a fight."

"Wait, what?! Generals are supposed to be hard to defeat, but you're saying it was easy?"

"Yeah, Zim is really good for killing everything." I said with a shrug.

Kura and Megumin stood there, in total shock.
